The Best Lab-Grown Diamond Jewelry To Buy Now and Love Forever

Best Lab-Grown Diamond Jewelry

With the rise of lab-grown diamond jewelry, a precious pair of earrings or a special signet ring is more readily available—and affordable—than ever before.

While some skepticism existed around lab-grown diamonds when they were first released, consumer understanding has shifted and popularity has grown. “[Lab-grown diamonds] have the same chemical, physical, and optical properties as mined diamonds,” says Mona Akhavi, president of the jewelry brand Vrai. This means that to the naked eye, it’s impossible to tell the difference. Supply is not limited in the same way that it is for mined diamonds, which means that lab-grown diamonds can be priced lower and more consistently.

In addition, since labs have the power to choose exactly what size and specification of diamond to produce, there’s an ability to react more deftly to jewelry trends or shifts in consumer preferences. That could mean everything from size to color to quality (e.g., how many inclusions, or flaws, are present). “Laboratory-grown diamonds can span the full rainbow of colors through growth and color treatment techniques,” says Ulrika D’Haenens-Johansson, a diamond researcher at the GIA. “In response to market demand, most laboratory-grown diamonds are in the D-to-Z range of colorless diamonds, though attractive yellow, blue, and pink colors are also available.” She adds that they can also range from tiny accent-size stones to 30 carats.

Final Verdict

Lightbox’s Bezel Studs are so timeless and practical for everyday wear that you really can’t go wrong. We especially love that they’re offered in two color options, white and yellow gold, so you can choose your preference. At $1,200, they’re certainly an investment, but what better investment to make? After all, if you’re going to splurge, you want something that can work for your lifestyle and won’t go out of fashion. However, if you’re looking for a more budget-friendly option to get your diamond fix, we put our weight behind Clean Origin’s Emerald-Cut Necklace for roughly half the price.

What to Look for When Buying Lab-Grown Diamond Jewelry

Materials

“Not every lab-grown diamond is made the same way,” says Akhavi. “Many producers use processes that actually produce emissions and pollution as they use fossil fuels to power their equipment.” Our top brand, Lightbox, grows its stones using entirely renewable energy sources, but has pledged to reduce its total emissions by one-third in the coming years (you can read the details here). However, shoppers can go a step further and look for diamonds that are created with zero emissions if that is of utmost importance to them.

When it comes to purchasing lab-grown diamond jewelry, you also want to be mindful of the metals used. For quality and longevity, avoid gold-fill or gold plating, and opt for pieces that are made with pure gold or platinum. You also want to research the purity of metal that is right for you. Higher purity gold, like 24 or 22 carats is softer, making it better suited to jewelry you wear on special occasions. Gold with a lower purity like 18, 14, or 10 carats is generally more durable and suited to everyday wear.

GIA Certification

Diamonds can be GIA certified, receiving a grade based on the four Cs (cut, clarity, color, and carat weight). When purchasing a diamond that is GIA-certified, you have the assurance of its quality and value.

The Four C’s

The quality of a diamond is distinguished by the four Cs. The first is cut, not to be mistaken by the shape, which speaks to how well-proportioned the diamond’s internal and external angles are. How well a diamond is cut directly impacts its brilliance, and the grading ranges between poor, fair, good, very good, and excellent, according to GIA’s standards. Meanwhile, the clarity speaks to how flawed the piece is. The grading scale here goes from “Included” (I) to “Flawless” (FL) with multiple stages in between. A chart provided by Vrai breaks this down further and can better help you assess the specifications of a piece of lab-grown diamond jewelry you’re looking to buy.

Color tells us the natural hue of the diamond. The closer it leans to colorless, the higher it is valued. GIA rates them from D to Z, with the former being completely colorless and the latter considered to have the brownest hue and thereby less valuable. Finally, carat refers to the size of the stone based on how much it weighs.

Shape

The shape refers to the geometric outline of the diamond and is not part of the four Cs. There’s a wide variety of them, though you can find the most common ones in a list provided by Brilliant Earth here. It includes round, oval, cushion, pear, marquise, emerald, asscher, and more.

FAQ

Do lab-grown diamonds look different from natural ones?

All diamonds have the same chemical structure and are made of carbon. According to D’Haenens-Johansson, it can be difficult to tell the difference between lab-grown and mined diamonds once they are cut and polished. “At GIA, gemologists and scientists rely on advanced instrumentation and decades of research to analyze minute differences in the atomic-level structure and other aspects that are unique to natural and laboratory-grown diamonds,” she says. “Conclusively revealing their origin as natural or laboratory-grown and

any treatments to alter their color or clarity.”
What are the advantages of buying lab-grown diamond jewelry?

D’Haenens-Johansson sees the availability of lab-grown diamonds as an advantage when deciding what to buy. Because lab-grown diamonds have a lower price point, there is more variety for jewelry lovers when investing in a new piece.

The social and environmental impact of a diamond can also be important to acknowledge. “A mined diamond can exchange hands up to 15 times from excavation to cutters to distributors and retailers, and each time the price is marked up and that markup is transferred to the consumers.
How do you care for lab-grown diamond jewelry?

“Diamonds are rated 10 on the Mohs scale of hardness, which makes them one of the toughest gem materials to scratch. For this reason, diamonds are very durable for everyday wear,” D’Haenens-Johansson says. To care for them, keep things simple, and soak them in water with the addition of a few drops of mild dish soap. Once they’ve had the time to soak, gently scrub them, which can help to remove any leftover buildup.
